"Patient safety, including appropriate use of our products, remains one of Endo's top priorities, and we are proud to announce that almost all remaining inventory of the original formulation of OPANA ER has been utilized," stated Julie McHugh, Chief Operating Officer for Endo Health Solutions. "We are passionate about the benefits of our reformulated product and hope to collaborate with the FDA to make crush-resistant formulations of long acting opioids the new standard of entry to the market."

With the intent of helping drive appropriate use of OPANA ER, Endo ceased production of the original formulation and began manufacturing only the version employing INTAC Technology in February 2012. For information about INTAC technology, visit: www.intac.grunenthal.com.

Additionally, Endo recently submitted two Citizen Petitions (CP) encouraging the U.S. Food and Drug Administration (FDA) to partner with the company in an effort to employ standards that will better manage patient access to vital pain management medications like OPANA ER while also helping drive appropriate use of the products.

Specifically, Endo's CPs call for:

A determination that the non-crush-resistant OPANA ER was discontinued from sale for reasons of safety when not taken as prescribed

The requirement that any abbreviated new drug applications (ANDA) referencing OPANA ER contain data and information demonstrating that the proposed ANDA product is similarly crush-resistant as the reformulated OPANA ER designed to be crush-resistant

The classification of crush-resistant technologies, such as the reformulated, crush-resistant OPANA ER, as a new dosage form in the FDA's Orange Book

Confirmation that any ANDA referencing the original non-crush-resistant OPANA ER will not be identified in the FDA's Orange Book as therapeutically equivalent to the reformulated OPANA ER designed to be crush-resistant

"As a leader in pain management, Endo supports the appropriate use of long-acting opioids. In 2007, we began the development of a formulation of OPANA ER designed to be crush-resistant because it was the right thing to do for patients, physicians and society in general," said Ivan Gergel, M.D., Executive Vice President, Research & Development, Chief Scientific Officer of Endo Health Solutions. "We are now pleased to offer the reformulated OPANA ER to patients as the only long-acting form of oxymorphone in a variety of strengths that are designed to be crush-resistant. We are encouraging the agency to ensure any future generics of OPANA ER are held to the same development standards before they are made available to the public."
